UNITED NATIONS – The United States is pressing the U.N. Security Council for the first time to confront the escalating problem of sexual abuse and exploitation by U.N. peacekeepers, which has undermined the credibility of the United Nations.

The United States is the biggest financial contributor to the U.N.’s far-flung peacekeeping operations, and U.S. officials said Friday the Obama administration wants the council to send a strong signal that it will not tolerate sexual crimes by troops and police sent to protect vulnerable civilians, especially children.

The council resolution drafted by the U.S. is a response to a new report by Secretary-General Ban Ki-moon detailing the 69 allegations in 2015 and for the first time naming the countries of alleged perpetrators.

“I am ashamed to call myself a peacekeeper when I think of some of these cases,” Undersecretary-General Atul Khare told reporters Friday. “Anyone serving under the U.N. flag and preying on the vulnerable is truly an abomination.”

Of the allegations in 2015, 23 allegations involved sexual activity with minors.

If approved by the U.N.’s most powerful body, the binding resolution likely would be the strongest pressure so far on countries contributing to peacekeeping missions to deal with sexual abuse and exploitation in their ranks. The U.N. has over 100,000 peacekeepers serving in some of the world’s most volatile and poverty-stricken areas.

Of last year’s allegations, 38 involved military personnel, 16 involved international police, and 15 involved U.N. staff or volunteers in peacekeeping missions. The report said 15 allegations involved rape of people over the age of 18. Paternity claims were associated with 15 allegations.

Over half of the allegations were made in two of the U.N.’s 16 missions: 22 against peacekeepers in the Central African Republic and 16 in Congo.

The mission in the Central African Republic, or CAR, has made headlines for months with reports of peacekeepers in the impoverished country trading sex for money and sexually abusing minors.

The United Nations has been under pressure to act after an independent panel in December described the world body’s “gross institutional failure” in handling allegations against French and other peacekeepers in CAR. That report said the months-long delay in addressing children’s accounts of abuse had led to even more reported assaults.

The secretary-general’s new report, obtained Thursday by The Associated Press, outlines new measures such as launching immediate response teams to collect evidence, calling on countries to send investigators to probe allegations against their troops, and ensuring that victims are not frightened away from reporting alleged abuse.

The U.N. already has begun acting on its vow to repatriate troops over alleged abuses, recently sending home military units from Congo and the Republic of Congo from CAR.

Often no one is punished because peacekeepers come under the legal jurisdiction of their home countries. “We have no authority to prosecute,” Khare said.

The secretary-general called for on-site court-martials of alleged perpetrators and DNA testing to identify them. He urged the 193 U.N. member states to update their national laws to ensure they apply to sex crimes committed by their citizens serving in U.N. peace operations.

He also asked countries to transfer the money withheld from U.N. personnel whose allegations of sexual abuse and exploitation have been substantiated to a victims’ trust fund.

The proposed Security Council resolution would endorse the secretary-general’s decision to repatriate U.N. troops or police if there is a pattern of exploitation and abuse by their unit, U.S. officials said, speaking on condition of anonymity because consultations have been private.

The proposed resolution also would ask the secretary-general to repatriate and replace military units or police if the country that sent them doesn’t investigate allegations, hold the perpetrators accountable or inform the U.N. of progress in its investigation, the U.S. officials said.

Countries contributing troops to U.N. peacekeeping operations are sensitive about interference from the United Nations, so it’s unclear whether the council will approve the proposed resolution.
